By IPv4 address space that makes it the 954th-largest of the 79,540 networks we see originating IPv4, and the 13th-largest of 456 in Thailand. It is seen behind 4 upstream networks, most often AS45430 (SBN-IIG/AWN-IIG transit provider) and AS23884 (Proen Corp Public Company Limited.), and in front of 76 downstream networks.

Networks observed one and two hops upstream of AS45458 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
